               The references applied by the examiner are:                            
          Arendt et al. (Arendt)        5,204,316           Apr. 20, 1993             
               (filed Apr. 2, 1990)                                                   
          Sato et al. (Sato ‘699)       5,288,699           Feb. 22, 1994             
               (effective filing date Dec. 6, 1990)                                   
          Sato et al. (Sato ‘123)       5,610,123           Mar. 11, 1997             
               Claims 1, 3, 4, 6 to 8 and 10 to 12 stand rejected on the              
          following grounds:                                                          
          (1) Unpatentable over Arendt in view of Sato ‘699, under                    
          35 U.S.C. § 103(a);1                                                        
          (2) Unpatentable for obviousness-type double patenting over                 
          claims 1 to 11 of Sato ‘123.2                                               
               On page 2 of their brief, appellants state that for purposes           
          of the appeal, the claims are considered in one grouping.                   
          Therefore, pursuant to 37 CFR 1.192(c)(7), we select claim 1 and            
          will decide the appeal based thereon.                                       



               1 A third reference, Meyer Pat. No. 5,206,211, was also                
          applied in this rejection, but the examiner states on page 2 of             
          the answer that the rejection based on Meyer is no longer                   
          maintained.                                                                 
               2 This rejection is not repeated in the examiner’s answer,             
          but at the oral hearing counsel for appellants agreed that it               
          should be considered as having been maintained by the examiner.             
                                          2
